DIAGNOSTICS 2.0 DIAGNOSTICS When the Narkomed 3 is powered up, each of the monitors performs a six-second self- diagnostic check and lamp test. The display window on each monitor should show a power-up code number, and all LED indicators and backlit labels should illuminate. The left-hand CRT will then show the Centralert Alarm display and the right-hand CRT will show the Data display.
